You should add a new character and he's called Fred from the Scooby doo series. everytime you get 3 problems wrong, Fred will be angry and give you a Concussion. the concussion will make you unable to move for some seconds. But, if you get 9 Problems right which is impossible in Non-endless modes, Fred will be happy and give you a random item. He only gives very useful items. He doesn't give items like WD NoSquees. When he is chasing you, you can use an item called Metal Ruler to hit his head and Fred Will no longer give you Concussions for rest of the game. When you hit Fred's head, He will say ''Okay Okay, i won't Give you concussions anymore. Just don't hit my head anymore.''. his Text to Speech voice is Paul.
Here's his angry self: You can make your sprites. It's recommended that Fred's Sprites look like comedy world.
Also, when principal sees you hit Fred's head, He will send you to dentention but he will send you to a shorter detention than usual because he knows that Fred gives you Concussions. When Principal Sees Fred give you a Concussion, he will send Fred to Detention as Twice as long as Player's Next Detention.
Here's some examples: If Player's Next detention is 5 seconds, Give Fred 10 seconds of Detention. If Player's Next detention is 25 seconds, Give Fred 50 Seconds of Detention.
